invention" relates'- generali to aniniprcved cabinet for the reception of tracirigs, drawings, prints; and't1 other slieets'which must be maintained? non-folded condition for subsedirent use ;1 andirr particular the inventonis directed to; and'- it' isthev principal cbi'ectito provide; sheet hanger arranged to receive and suspend arelatively large numberof sheets Within amini'iiium of space'iand positonl for' ready access toi-cacha- A frther object fth'e invention istoprovide a sheetl hanger which includes; in a suitable' hou'sr ing cr cabinet', auriique assembly cf supporting wires mounted in the" calairiet,` and wire engaging clips attached to the sheet and releasably suspended from said Wires.

An additional object of the inventi-on is toprovide a sheet hanger, as above, wherein the suspending clips are arranged so that they remain on .the sheet when the latter is removed from the cabinet, and can pass through an automatic blue printing machine, for example, without damage to either the clip or the machine.

It is also an object I0I? the invention to provide novel connector units between the ends of the horizontal supporting wires and the sides of the cabinet; said units being adjustable to properly tension said wires.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for lthe purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the 'following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a front elevation of the sheet hanger as in use; the front curtain or drape being shown partially open.

Figure 2 is an enlarged fragmentary transverse section on line 2 2 of Fig. 1.

Figure 3 is an'enlarged fragmentary sectional elevation of one of the wire end connector units.

Figure 4 is an enlarged fragmentary elevation of one of the suspending clips as attached to a movement along a: horizontal wire 5 mounted in the cabinet' adjacent' the top andv front thereof.`

` The'pcabinet is preferablyof knockdown type So that it' maybe readily dismantled for movement from place toplac'e if necessary.

Within tliecabinet immediately bel-ow butspacedfrom thet'op 3, there are two' pairs of horizon-` tal wires 6, one pair being adjacent the front of the cabinet while the other' pair is adjacent the' back of the cabinet; the Wires of each pair being parallel and spaced apart laterally relative to each other, andthe corresponding Wires of `the separate pairs being spacedV an equal distance, as clearly shown in Fig. 21 All of the wires are in thesam'e horizontal pla-ne', and at their ends are connected with theV sidel panels I`v of' the cabinet by mea-ns ofV tensioning units', indicated generally at 1, each of which is constructed as follows:

The wires 6 at their ends pass through ports 8 in the side panels I into an enclosure or chamber 9 formed by a'cap I0 xed on the exterior of the side panel I in surrounding relation to port 8. The outer end of cap I0 is formed with a central opening II through which a cap screw I2 projects, the head I3 of said cap screw being in chamber 9. The cap screw is formed with a 1on- Igitudinal and central bore I3 through which the corresponding wire 6 is threaded from the head through the cap screw and bent laterally, as at I6. A nut I1 is threaded on the cap screw eXteriorly of A the cap I0 and abuts the outer end thereof. With tightening of the nut I1, the corresponding wire o 6 is placed under tension. To prevent loop I5 from pulling through bore I3, a transverse pin P may be disposed in the loop.

The sheets of tracings I8 or the like are suspended in the cabinet in face to face relation and facing the side panels I. In other words, one side edge of the sheets I8 is presented adjacent the iront of the cabinet, while they other or opposite side edge is disposed adjacent the back panel 2.

The sheets I8 are individually suspended from the wires 6 by means of a pair of suspending units indicated generally at I9 secured to and spaced along the upper edge of said sheets; such units cooperating with corresponding ones of the pairs of said wires. In order to permit of the hanging of a maximum number of sheets, without interference by the suspending units I9, the latter are mounted on alternate sheets so as to cooperate alternately with the different Wires of said separate pairs. It will thus be seen that the disposed above but substantially abuts and extends along the upper edge 2| of the sheet I8. A length of adhesive tape 22 is looped through the eye and is adhered to the adjacent portion of the sheet I 8 on opposite sides thereof. To further assure against yseparation of the adhesive tape 22 from sheet i8, metal staples 23 may be projected through the adhesive tape and the po-rtion of the sheet therebetween.

While this specication sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is: l n

1. A sheet hanging unit adapted to be secured in plurality and in spaced relation along the upper edge of a sheet so as to suspend the latter from a horizontal wire or the like; said unit comprising a horizontally elongated eye disposed A hook 24 extends upwardly from the eye 20 substantially centrally of the ends of the latter and engages over the corresponding wire 5; such v hook at its outer or free end being formed as anvv elongated leg 25 which extends at a downward and outward slope to a termination short of but adjacent the upper edge of eye 2E). The space 2S between the lower end of leg portion 25 and eye 20 is less than the diameter of Wire 6, so that the suspending units are placed on or removed from the wires with a snap action, which is possible due to the resiliency of the leg portion 25 relative to the remainder of the hook.v

In order to place a sheet in the cabinet, or to remove a sheet, the front curtain 4 is opened to the necessary extent and the two suspending units I9 are either engaged with or detached from the proper ones of the wires 6.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

above and extending along the upper edge of the sheet with the lower run of the eye adjacent said edge, means connected between said lower run of the eye and the sheet, securing the eye to the same, a Wire eng-aging hook upstanding from the upper run of said eye intermediate the ends of the latter, said hook being vertically elongated and the free leg thereof being extended down-l wardly to a point closely adjacent but short cf said upper run of the eye; suchextendedl leg being resilient in'relation to the eye, and the space between the lower end of said resilient leg and said upper run of the eye being less than the diameter of the supporting wire.

2. A sheet hanging-unit as in claim l in which said extended leg of the vertically elongatedvhook extends at a'downward and outward slope, the lower'end of said extended leg terminating at a point, lengthwise of said elongatedl eye, adjacent but short of one end of said eye. I
